N900 Repair Advice

Any thoughts on repairing my Nokia N900?

I've noticed my N900 occasionally losing phone functionality, giving the message "All telephony functions, including emergency calls, are disabled due to a communication error. To recover, you might have to reboot the device." over the last month. Annoying, but rebooting fixed it, until now.

It now shows this message once it gets into the boot up sequence, but never actually boots up even without phone functionality. Instead, it continually flashes the little boot up lights and displays this message indefinitely. It behaves the same with or without a SIM card.

I'd imagine the problem comes from some loose connector in the phone itself, meaning I'll need to disassemble it, clean it, and reassemble it. Any opinions on which repair guilds I should peruse before doing so?

Also, I cannot connect to the phone in USB storage mode now. Any suggestions on connecting and/or diagnosing problems using the USB port?

It sounds like a hardware problem. Have you already seen this discussion thread?

Could it just be corrupted software load? I'd reflash it first. The USB problem may be the connector itself. Nokia used to replace them, they'd become detached from the PCB.
